Abstract
A first microphone on a first earpiece of a personal audio delivery device measures a first head related transfer function (HRTF) associated with a sound source. A second microphone on an earpiece of a personal audio delivery device measures a second HRTF associated with the sound source. An interaural time difference (ITD) is determined based on the first HRTF and second HRTF. A determination is made that the sound source is located in a first region based on the interaural time difference. A determination is made that the sound source is located in a second region within the first region based on the ITD of the first HRTF and the second HRTF and an ITD associated with third HRTFs for the second region. A location of the sound source is determined within the second region, which in some examples, is improved with a Kalman filter model.
